Communication, Counter and Pulse
SECTION 4
12 to 15
End code selection for no-protocol communications
0: Disables end code; 1: Enables end code in DM 6649; 2: Sets end code of CR, LF.
(Any other setting disables the end code, causes a non-fatal error, and turns ON AR 1302.)
Word(s) Bit(s)
Function
00 to 07
Start code (00 to FF)
(This setting is valid only when bits 8 to 11 of DM 6648 are set to 1.)
DM 6649
08 to 15
When bits 12 to 15 of DM 6648 set to 0:
Sets the number of bytes to receive. (00: 256 bytes; 01 to FF: 1 to 255 bytes)
When bits 12 to 15 of DM 6648 set to 1:
Sets the end code. (00 to FF)

Peripheral RS-422/485 Port Communications Settings
The following settings are effective after transfer to the PLC.
If the 3G3MV-P10CDT Unit’s Communications Switch is ON, communica-
tions through the peripheral port are governed by the default settings (all 0)
regardless of the settings in DM 6650 through DM 6654.
The 3G3MV-P10CDT’s Communications Switch setting has no effect on
communications with a Programming Console connected to the peripheral
port or Support Software set for peripheral bus communications. The
3G3MV-P10CDT Unit will auto-detect either Programming Device and auto-
matically establish communications.
Word(s) Bit(s)
Function
00 to 03
Port settings
0: Standard (1 start bit, 7 data bits, even parity, 2 stop bits, 9,600 bps), Host Link unit
number:
0
1: Settings in DM 6651
(Any other setting will cause a non-fatal error and AR 1302 will turn ON.)
04 to 11
Not used.
DM 6650
12 to 15
Communications mode
0: Host Link or peripheral bus; 1: No-protocol
(Any other setting causes a non-fatal error and turns ON AR 1302.)
00 to 07
Baud rate
00: 1,200 bps; 01: 2,400 bps; 02: 4,800 bps; 03: 9,600 bps; 04: 19,200 bps
